abstract

abstract        background and objective: herpes simplex encephalitis is a life-threatening consequence of the central nervous system (cns) infection with herpes simplex virus (hsv). although it is a rare disease, mortality rates reach 70% in the absence of therapy and only a minority of individuals can return to normal function. the aim of this study was to determine possible correlation between hsv infection and the incidence of encephalitis in patients with neurological signs.         methods: overall, 152 csf samples were tested from patients with neurological signs referred to mahdieh clinical laboratory in isfahan from 2010 to 2013. after cerebrospinal fluid (csf) collection, dna was extracted and real-time polymerase chain reaction (pcr) was performed for hsv detection.           results: of 152 patients tested, 50 were diagnosed with encephalitis. hsv dna was present in the csf of 13 patients with encephalitis. hsv was significantly higher (p< 0.05) in patients with encephalitis, which shows the significance of infection as an etiological factor of this disease. about 60% of the encephalitis cases were in age range of 1-24 months.          conclusion: according to the findings of the present study, cesarean section is recommended for hsv-positive mothers. a routine real-time pcr test is suggested for hsv detection in patients with encephalitis to avoid unnecessary antiviral treatments.

Detection of Herpes Simplex Virus DNA in Pseudoexfoliation Syndrome

Background: Pseudoexfoliation syndrome is one of the most common identifiable causes of open angle glaucoma. It has unknown etiology and pathogenesis. Infection, possibly viral, is one of the proposed pathogenic mechanisms in this condition. In the present study the presence of herpes simplex virus (HSV) in specimens of anterior lens capsule of patients with pseudoexfoliation syndrome has been ...

Comparative evaluation of colorimetric microtiter plate systems for detection of herpes simplex virus in cerebrospinal fluid.

In the past few years, application of the PCR to the detection of herpes simplex virus (HSV) DNA in the cerebrospinal fluid (CSF) from patients with encephalitis and meningitis has become standard laboratory practice. However, from an operational perspective, the true diagnostic value of PCR in this setting is yet to be realized because most laboratories subject the amplification products to le...

Prevalence of Herpes Simplex Virus type-1, 2 and Varicella Zoster Virus (VZV) in Eye Infection

Abstract Background and Aims: Herpes simplex virus (HSV) is a common cause of corneal disease and is the leading infectious cause of corneal blindness among developed nations. This study is aimed to provide an estimation of the incidence of Herpes Simplex Virustype-1, 2(HSV1, 2) and Varicella Zoster Virus (VZV) in tears and swab from eye infection by polymerase chain reaction (PCR) in eye ...

Impact of Herpes simplex virus load and red blood cells in cerebrospinal fluid upon herpes simplex meningo-encephalitis outcome

BACKGROUND Herpes simplex encephalitis (HSE) often leads to severe disability or death. Factors usually associated with outcome include Simplified Acute Physiology Score, age and delay of initiation of acyclovir treatment.Our aim was to determine the impact of Herpes simplex virus (HSV) load in cerebrospinal fluid (CSF) upon HSE outcome. METHODS We retrospectively determined HSV load in the C...

Neonatal herpes simplex virus infection

Neonatal herpes simplex virus (HSV) infections may be caused by either herpes simplex virus type-1 (HSV-1) or herpes simplex virus type-2 (HSV-2). In the United States, HSV-2 is responsible for 75% of genital and neonatal infections, while HSV-1 causes the rest. HSV-1 more commonly affects the oropharynx, the eyes and the central nervous system.1,2 It is estimated that 20 to 30% of sexually act...
